Hair care giant Pantene was all over the list, but did it nab the no. 1 spot?

Why it's great: "I have paid big bucks at a salon for a deep conditioning treatment that I did not like as much as this," says a reader. Others love that it "makes my hair really shiny and silky" and "I rarely have any breakages or split ends." Readers say, "If you have super dry hair … this is the conditioner for you," because it "makes my over-processed hair feel like hair again, not straw."
